A pregnant woman must eat for two- why?

It is a common misconception that a pregnant woman should eat for two. In reality, a pregnant woman only needs to consume additional calories for one extra person, not two. It is important for pregnant women to maintain a balanced and nutritious diet to support the healthy development of the fetus and maintain their own health during pregnancy. Eating excessive amounts of food can lead to weight gain and other health complications for both the mother and baby. It is recommended that pregnant women consult with a healthcare provider to determine their specific nutritional needs during pregnancy.
